a switch cabinet

Abstract

The invention discloses a switch cabinet, which relates to the field of electrical equipment. A switch cabinet comprises a cabinet body, Top and bottom panels, An exhaust pipe is arranged through thetop plate, A low end surface of that top plate is provided with a cavity, A dry powder fire extinguishing agent and a pair of sealing plates are arranged in the cavity, one side of the sealing platesfacing away from each other is hinged to the lower end sidewall of the cavity and the other side is in contact with each other, The upper end surface of the top plate is provided with a support seat,the support seat is provided with a support rod, a pair of sealing plates are provided with a thin rope spanning the support rod, a circular arc-shaped cutting knife for cutting the thin rope is hinged on the support seat, and a driving mechanism for driving the cutting knife to rotate is provided on the exhaust pipe. The invention has the following advantages and effects: When a fire breaks out,the sealing plate is opened and the dry powder fire extinguishing agent is sprayed by using the thick smoke thrust to control the cutting knife to cut the rope, and the fire-retardant and fire-extinguishing agent is used to the components, so as to avoid the fire spreading, protect the other components from being burned, and avoid excessive economic losses.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a switch cabinet. Background technique [0002] Switchgear is a kind of electrical equipment, its main function is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. [0003] The Chinese patent with the authorized announcement number CN207082759U discloses a switchgear. The switchgear includes a switchgear box, and a heat dissipation device is arranged in the switchgear box. Air mechanism, a cooling mechanism that provides cold air for the air supply mechanism. [0004] When the above switchgear is in use, various components need to be installed in the switchgear box first, but when a ce...

Problems solved by technology

[0004] When the above switchgear is in use, various components need to be installed in the switchgear box first, but when a certain component in the switchgear box has a large load and a fire occurs, if the fire is not extinguished in time, the fire will spread , causing more components to be burned, which will cause huge economic losses and needs to be improved
